christine, that the weather conditions aren t ideal today. but they re obviously good enough to get every asset they ve got back down there. there is a window down here. we re being told that weather could close in at anytime. this is a very, very difficult part of the planet to predict the weather patterns because it is so far south. storms can blow up very quick lip. every hour virtually counts. every hour is critical because there s only a certain amount of time that the data from these flight recorders will be broadcasting. they ve got to narrow on where those are. time is so critical here. that s right. the u.s. have sent two very sophisticated devices which are now in perth. one is a locator. it s dragged behind a boat, a ship, to look specifically for the beacons, the pinging coming from the flight recording boxes which are somewhere, we assume, on the bottom of the sea.
scene, are also making their way there. this is the biggest day of the air search operations. ten planes going up today to search that area. andrew, before we heard the news about the debris being spotted by these chinese search crews, there was news that the u.s. is sending a super sensetive pinger locater. what can be read into that? reporter: again, it s another link to the fact that authorities are seeing this still as the most positive lead, the strongest lead they have. what a pinger is needed for is to locate any distress beacons which may be deep, deep under water. now, the range of these distress beacons, which would identify where the flight recording boxes, the all-important flight recording boxes is, the range on those is just a couple of miles. in some places in the ocean,
cost out there sort of thing to do. why has that not happened? those are things as i think we move into the future they are talking about 90-day batteries that may be able to give off signals. also the potential there would be streaming, that would be targeted to be normal until there s an anomaly at which point in time as soon as the plane goes off the charted course it gives you more information. this is the kind of thing that s capable to be done through satellite technology but we re not there yet in the form of utilizing it in that way. so, the other thing that i learned and we relearn these things when we have these unfortunate tragedies happen and that is that the flight recording of what s going what s being said inside the cockpit actually only picks up the final two hours before landing or crash. what about constant? what would be wrong with that?
